when using git svn, sparse checkout of central repository may achieved along lines of git clone -s url-to-root --include-paths 'dir1|dir2|dir3' after using setup time, add directory dir4 tracked. directory has existed in many commits have checked out. editing variable svn-remote.svn.include-paths running git config --edit does not have desired effect on git fetch (only files changed in future commits checked out changed; not immediately), , following not check out dir4: git svn fetch --include-paths dir4 i think following work ineffective due refetching revisions since first revision @ dir4 appeared first time (let's call rev): git svn reset -r rev git svn fetch --include-paths dir4 git svn rebase what better way of tracking dir4? if not care history of dir4? is there better way initial sparse checkout git-svn if suspect want change list of tracked directories later? have tried starting listing directoreis not fetched in original commit, not know how...
